An ancient creature "woke up" after 100 million years under the seabed

Deep beneath the seabed, enclosed in layers of rocks 100 million years old, a form of life has quietly hibernated to this day. It is nothing like Godzilla or Megalodon, but it shows that life on Earth can survive in the most extreme and bizarre conditions.

Scientists have recently discovered a colony of microbes that live under the seabed and can survive in rock sediments for up to 100 million years with very few nutrients. The microbes recovered in the laboratory where they emerged from hibernation and began to multiply.

The journal Nature Communications reports that the team of scientists found the microbes after collecting a sample of sediment 75 meters below the seabed in the southern Pacific Ocean at a depth of about 5,700 meters. The microbes were successfully "revived" through a process that took scientists 10 weeks.

"These are the oldest microbes brought back to life by the marine environment. "Even after 100 million years of starvation, some microbes can grow, multiply and engage in a variety of metabolic activities once they are brought back to the surface," said Stephen D'Hont, a scientist and professor of oceanography at the University of Rhode Island.
